Embedded Programming with Modern C++  is highly valuable for each professional programmer.

In the past, embedded and system programming have had their pitfalls, but modern C++ has been designed to be a better language for this type of development, addressing the previous pitfalls/requirements explicitly. What are these requirements? Embedded systems deal with safety-critical systems, meaning they must guarantee high performance combined with limited resources, while also working in parallel.

The scope of this course goes beyond just embedded programming. Developers who write servers, games, or trading systems may especially benefit from this course because they also have to deal with safety-critical systems, high performance, reduced resources, and parallel execution in their jobs.

To get the most out of the course, you only need a basic understanding of C++. Building off this understanding, this course goes over all the essentials of embedded programming with Modern C++.

Let's get started!

Embedded Programming with Modern C++

**Enumerations** conveniently define integer constants with names. These integer constants are called **enumerators**. Let’s go over some of the drawbacks of using classic enums. 

# Drawbacks of Enumerations in Classical C++
A short reminder. Three drawbacks of enumerations:

1. The enumerators implicitly convert to `int`.
2. They introduce the enumerators in the enclosing scope.
3. The type of the enumeration cannot be specified.

Regarding point 3, enumerations cannot be forward declared since their type unknown. We can only the guarantee for the enumerators in classical C++. The type must be integral and large enough to hold the enumerators.

Points 1 and 2 are more surprising.

In this lesson, we will learn about Enumerations or Enums.
